Read Webtoon Vicious Dog online in English. Also known as The Mad Dog, Mad Dog, Akuken, and 悪犬.

In a country where the juvenile justice system has been reshaped, young offenders are sent to a so-called reformatory that hides something far uglier than rehabilitation. Gen Amamori is an ordinary high school student crushed by relentless bullying, until a brutal incident involving his beloved dog pushes him past the limit and changes his life forever.

Locked inside a facility ruled by fear, fists, and status, Gen is thrown to the very bottom from the moment he arrives. Survival is no longer about being right or wrong. It is about learning how to stand, how to endure, and how to take back the dignity that was stolen from him. With violence closing in from every side, his weakest days may become the beginning of something far more dangerous.

This series may appeal to readers who enjoy revenge action, psychological survival drama, and gritty underdog stories.
